From: Atmospheric chemosynthesis is phylogenetically and geographically widespread and contributes significantly to carbon fixation throughout cold deserts

Fig. 1

The relative abundance of major bacterial and archaeal phyla residing in triplicate desert soils from Alexandra Fjord Highlands (AFH), Spitsbergen Svalbard (SS), Tibetan Plateau (TP), Mitchell Peninsula (MP), New Harbour (NH) and The Ridge (TR) are displayed; phyla with <2% relative abundance in all soil samples were grouped to the “Other” phyla. Actinobacteriota dominate all sites, particularly The Ridge (average 77.9%), TP (average 62.9%) and Mitchell Peninsula (average 45.2%). Photosynthetic Cyanobacteria are extremely scarce within NH, TP and The Ridge samples (<0.07%), with greater average abundances observed at Mitchell Peninsula (0.6%), SS (0.4%) and Alexandra Fjord Highlands (2.0%). Ca. Eremiobacterota and Ca. Dormibacterota dominate Mitchell Peninsula microbiomes (average 7.8% and 3.6%, respectively) and are present at lower levels within SS and Alexandra Fjord Highlands. Archaea are minor members of these ecosystems (average relative abundances; <0.2% within The Ridge, Mitchell Peninsula, NH; 2.6% within TP; 0.5% within SS; 1.2% within Alexandra Fjord Highlands).
